And when guiding the chain terminal 30 which is the connection body of the terminal 20, both the guide bodies 56b and 57b are advanced. As a result, the terminal 20 having a relatively short length L1 is guided at a certain vertical position between the opposing surfaces of the recesses 56g and 57g. Further, when guiding the chain terminal of the terminal 20B, since the insertion portion 22B which is the lower end of the terminal 20B is relatively long, the upper guide body 56b is advanced and the lower guide body 57b is retracted. As a result, the terminal 20B having an intermediate length L2 is guided at a certain vertical position between the opposing surfaces of the recess 56g and the feed groove 53g. Further, when guiding the chain terminal of the terminal 20C, the upper and lower guide bodies 56b and 57b are retracted because the terminal 20C is relatively long at both the connection portion 26C as the upper end portion and the insertion portion 22C as the lower end portion. Accordingly, the terminal 20C having a relatively large length L3 is guided at a certain vertical position between the upper and lower opposing surfaces of the feed groove 53g.

  Thereby, even if it is terminal 20,20B, 20C from which length differs, since the press-fit part 23 which is a connection part is guide | induced to the predetermined position hold | gripped with a pair of holding members 72 and 74, holding | grip and separation operation | movement mentioned later Can be performed more reliably. Further, by changing the advancing / retreating state of the upper movable guide part 56 and the lower movable guide part 57, it is possible to easily cope with the terminals 20, 20B, 20C having a plurality of lengths. In addition, it can respond similarly about the terminal from which length differs, such as a 2nd series.

  The terminal feed unit 58 includes a rotation drive unit 58a such as a stepping motor and a feed turntable 59. The rotation drive portion 58 a is attached to the upper surface of the attachment member 51, and the rotation drive shaft portion 58 b extends through the attachment member 51 on the side of the main guide member 53. As shown in FIG. 14, the feed rotating disk 59 is formed in a disk shape, and terminal feed protrusions 59a are formed at predetermined intervals on the outer periphery thereof. Each terminal feed protrusion 59a is formed in a projection shape that can be fitted into the terminal feed hole 23h, and the interval thereof coincides with the interval of the terminal feed holes 23h in the chain terminal 30. This pitch is substantially the same for the terminal series having the same width, here, the terminals 20, 20B, 20C belonging to the first series. The feed rotary disk 59 is rotatably supported by the rotary drive shaft portion 58b at a vertical position corresponding to the press-fit portion 23 and the terminal feed hole 23h of the chain terminal 30 fed along the feed direction S. Then, the feed rotating disk 59 is intermittently driven to rotate, so that the terminal feed protrusion 59 a of the feeding rotating disk 59 is arranged in the feed groove 53 g on one main surface of the main guide member 53. The terminal 30 is sequentially fitted into the terminal feed hole 23h of the terminal 30 so that the chain terminals 30 are sequentially fed along the feed direction S one by one.

  By the way, the widths of the second series of terminals 20D and 20E are different from those of the first series of terminals 20, 20B and 20C. Therefore, as shown in FIG. 15, if a terminal supply mechanism having a rotating turntable 59D having a different spacing from the terminal feeding protrusion 59Da is prepared separately, the second series having such a different width is prepared. It is possible to cope with terminal feeds for the terminals 20D and 20E. As described above, since the terminal supply mechanism 50 itself is detachably attached to the lower support plate 43 by a screw member 51S such as a thumbscrew, etc., depending on the type of terminal (particularly, one having a different width). And can be easily replaced.

<2.3. Terminal gripping part>
FIG. 16 is a front view showing the terminal gripping portion 70, and FIG. 17 is a side view showing the terminal gripping portion 70.

  The terminal gripping portion 70 has a gripping main body portion 71, a pair of gripping members 72 and 74, and an urging member 76.

  The grip body 71 is formed in a substantially square thick plate shape, and is configured to be detachable from the terminal grip support mechanism 80. Here, the gripping main body 71 is detachably attached to the terminal gripping portion mounting portion 88 on the lower surface side of the lower gripping portion support plate 84 by a screw member 71S such as a thumbscrew. As a configuration for detachably attaching the grip body 71, a clamp mechanism, a fitting and fixing structure, or the like may be used. The terminal gripping portion 70 is supported by the terminal gripping portion support mechanism portion 80 so as to be movable toward and away from the circuit body 10.

  The pair of gripping members 72 and 74 are supported so as to be openable and closable between an open state in which the terminal 20 can be gripped (see FIG. 16) and an open state in which the gripping of the terminal 20 can be released (see FIGS. 26 etc.). More specifically, the pair of gripping members 72 includes a gripping member 72 that can be opened and closed and a gripping member 74 on the fixed side. The fixed-side gripping member 74 is formed as a long member, and the tip thereof is formed to have a width W1 that is substantially the same as the width of the press-fit portion 23 of the terminal 20 (see FIG. 17). The base end portion of the holding member 74 on the fixed side is attached and fixed in a fixed posture that substantially hangs down with respect to the holding main body portion 71. The gripping member 72 that can be opened and closed is formed as a long member, and the tip thereof is formed to have a width W1 that is substantially the same as the width of the press-fit portion 23 of the terminal 20 (see FIG. 17). The proximal end portion of the gripping member 72 is supported so as to be rotatable within a predetermined range with respect to the gripping main body portion 71 via a shaft portion 71a. Then, when the proximal end portion of the gripping member 72 rotates around the shaft portion 71a within a predetermined range, the pair of gripping members 72 and 74 can open the terminal 20 between the distal end portions thereof and the terminal 20 It is supported so that it can be opened and closed between an open state in which gripping can be released.

  In addition, an accommodation groove 72 g that is wider than the connection portion 26 and narrower than the press-fit portion 23 in the terminal 20 is formed on the inner surface of one gripping member 72. And between the front-end | tip part of a pair of holding members 72 and 74, while being able to hold | grip the press-fit part 23 among the terminals 20, the said terminal 20 can be pushed in the state which accommodated the connection part 26 in the accommodation groove | channel 72g. ing. This point will be further described later in the description of the operation.

  The urging member 76 urges the pair of gripping members 72 and 74 in the closed state, and here is constituted by a coil spring. The biasing member 76 is disposed in a compressed manner between the longitudinal intermediate portions of the pair of gripping members 72 and 74, and the pair of gripping members 72 and 74 are closed by the elastic force in the extending direction of the biasing member 76. Energized to the state. The urging member 76 may be a torsion coil spring, a leaf spring, rubber, or the like.

  Note that the terminal gripping portion 70 described above is intended for gripping the terminals 20, 20B, and 20C belonging to the first series. When the second series of terminals 20D and 20E having a larger width are to be gripped, the width W2 of the distal end portion of the pair of gripping members 72D and 74D is matched with the width of the press-fit portion 23D of the terminals 20D and 20E. What is formed in the thicker width W2 may be used (see a two-dot chain line in FIG. 17). Since the terminal gripping portion 70 is detachably attached to the terminal gripping portion mounting portion 88 on the lower surface side of the lower gripping portion support plate 84 by a screw member 71S or the like, the type of terminal (especially one having a different width) It can be easily replaced depending on the situation.

<2.4. Terminal insertion drive mechanism>
18 is a schematic front view showing the terminal insertion drive mechanism 100, and FIG. 19 is a schematic side view showing the terminal insertion drive mechanism 100. As shown in FIG.

  The terminal insertion drive mechanism 100 includes a gripping force applying unit 150, a separating force applying unit 160, a motor 102 as a single drive source, a first cam member 112, a second cam member 114, and a third cam member. 116, a first transmission mechanism 120, a second transmission mechanism 130, and a third transmission mechanism 140.

  The gripping force applying unit 150 is configured to be capable of applying a gripping force for gripping the terminal 20 by pressing the gripping member 72 that can be opened and closed among the pair of gripping members 72 and 74. More specifically, the gripping force applying unit 150 is formed in a long shape, and is a movable support member Q fixedly supported by the support housing 41 or the like (hereinafter, other than the support member 41 fixedly supported by the support housing 41 or the like). Similarly, the movable support member Q may be referred to as the movable support member Q)), and the distal end of the one gripping member 72 is located outside the distal end portion of the one gripping member 72 of the terminal gripping portion 70 at the gripping position. It is supported so as to be movable toward and away from the part. A roller 152 that is a rolling element is rotatably supported at the distal end portion of the gripping force applying portion 150, that is, the portion that presses the distal end portion of the gripping member 72. The pair of gripping members 72 and 74 can be moved closer to the circuit body 10 while the roller 152 is driven to rotate while the gripping force applying unit 150 presses the one gripping member 72 via the roller 152. It has become.

  Further, the gripping force applying unit 150 is biased toward the gripping member 72 by the gripping force applying unit biasing member 158. The gripping force applying unit urging member 158 is, for example, arranged to be compressed between the gripping force applying unit 150 and the movable support member Q so as to urge the gripping force applying unit 150 toward the gripping member 72. A coil spring or the like can be used. The biasing force by the gripping force applying portion biasing member 158 is larger than the force with which the pair of gripping members 72 and 74 try to open by the biasing member 76. Accordingly, when the gripping force applying unit 150 presses the gripping member 72 by the biasing force of the gripping force applying unit biasing member 158, the pair of gripping members 72 and 74 are closed against the biasing force of the biasing member 76. The terminal 20 can be gripped.

  In addition, a grip operation force receiving surface 157 that receives a force from the second transmission mechanism unit 130 described later is formed at the base end portion (outer end portion of the apparatus) of the grip force applying unit 150. The grip operation force receiving surface 157 is formed on an inclined surface that is inclined outwardly downward. The relationship between the grip operation force receiving surface 157 and the second transmission mechanism 130 will be described later.

  The separation force applying unit 160 is configured to separate the terminal 20 gripped by pressing the gripping member 74 on the fixed side out of the pair of gripping members 72, 74 so as to separate the terminal 20 from the front terminal 20. A force for displacing 74 can be applied.

  In other words, the terminal gripping portion 70 is attached to be displaceable via the displacement member 89. More specifically, a displacement member 89 is provided between the gripping part support plate 84 and the terminal gripping part mounting part 88. The displacement member 89 includes a rail body 89a attached to the lower surface of the gripping part support plate 84 and extending along a predetermined direction (here, the left-right direction of the apparatus), and a movable body 89b movable along the rail body 89a. Have. The terminal gripping part attaching part 88 is attached to the movable body 89b. The terminal gripping portion 70 is displaceable so as to be displaced laterally from the terminal supply port portion 50m while being attached to the terminal gripping portion mounting portion 88.

  The terminal gripping portion mounting portion 88 is provided with an auxiliary displacement force receiving portion 87 having a concave groove 87g extending in the vertical direction.

  The separation force applying portion 160 is formed in an elongated shape, and is moved outwardly from the distal end portion of the other gripping member 74 of the terminal gripping portion 70 at the gripping position by the movable support member Q, that is, a pair of gripping members. On the opposite side of the gripping force applying portion 150 with the 72 and 74 interposed therebetween, the tip end portion of the other gripping member 74 is supported so as to be able to approach and separate. A roller 162 that is a rolling element is rotatably supported at the distal end portion of the separation force applying portion 160, that is, the portion that presses the distal end portion of the gripping member 74. The pair of gripping members 72 and 74 can be moved closer to the circuit body 10 while the roller 162 is driven and rotated in a state where the separating force applying unit 160 presses the other gripping member 74 via the roller 152. It has become.

  In addition, separation operation force receiving surfaces 167a and 167b for receiving a force from a third transmission mechanism unit 140, which will be described later, are formed at the base end portion (outer end portion of the apparatus) of the separation force applying unit 160. The separation operation force receiving surfaces 167a and 167b are inclined surfaces that are inclined outward and are formed to face each other at a predetermined interval. The relationship between the separation operation force receiving surfaces 167a and 167b and the third transmission mechanism 140 will be described later.

  In addition, the separating force applying unit 160 is provided with an auxiliary separating force applying unit 168. The auxiliary separating force application unit 168 includes a long piece-like auxiliary support unit 168a extending upward from an intermediate portion of the separation force application unit 160, and a roller 168b as a guide member attached to the tip of the auxiliary support unit 168a. And have. The roller 168b is formed so as to be able to be fitted into the concave groove 87g of the auxiliary displacement force receiving portion 87, and the roller 168b moves as the separation force applying portion 160 moves the gripping member 74 in the pressing direction and the opposite direction. Are also moved together, and the auxiliary displacement force receiving portion 87 is pressed in the same direction or moved in the opposite direction.

  As a result, the terminal gripping portion 70 is displaced laterally under the force of both the roller 162 at the tip end of the separating force applying portion 160 and the roller 168b at the tip end of the auxiliary separating force applying portion 168.

  The motor 102 is configured by a stepping motor or the like, and is attached and fixed on the upper support plate 42 of the support housing 41. The shaft 104 that is rotationally driven by the motor 102 is disposed between the upper support plate 42 and the lower support plate 43 in a substantially vertical posture, that is, in a posture along the moving direction of the terminal gripping portion 70.

  The first cam member 112, the third cam member 116, and the second cam member 114 are fixedly attached to the shaft 104 in this order from the upper side to the lower side. The rotation of the shaft 104 causes the same rotation around the copper rotation axis. It is comprised so that it may rotate in synchronization with the rotation speed.

  The first cam member 112 is formed in a substantially disk shape, and has upper and lower cam surfaces 112 a that are uneven around the shaft 104.

  The first transmission mechanism portion 120 includes a first driven member 122 that is driven to move according to the uneven shape of the cam surface 112 a as the first cam member 112 rotates. The first driven member 122 is attached and fixed to the upper part of the upper gripping part support plate 84 so as to be positioned on the outer peripheral part of the first cam member 112. The first driven member 122 has a pair of driven rollers 122a disposed so as to sandwich the first cam member 112 from both sides. As the first cam member 112 rotates, the first driven member 122 having the pair of driven rollers 122a moves in the vertical direction according to the uneven shape of the cam surface 112a. In conjunction with the movement of the first driven member 122, the terminal gripping unit 70 integrated with the first driven member 122 via the pair of gripping unit support plates 84 and the support plate connecting member 86 is provided. The circuit body 10 is configured to move toward and away from the circuit body 10.

  That is, the circuit body support portion 48 moves toward and away from the circuit body 10 in a manner corresponding to the uneven shape of the upper and lower cam surfaces 112 a around the shaft 104. Here, the shape of the upper and lower cam surfaces 112a is such that the terminal gripping portion 70 is moved away from the circuit body 10 after the temporary insertion operation for moving the terminal gripping portion 70 toward the circuit body 10, and then the circuit body 10 is again formed. It is formed in a shape that allows the main insertion operation to move toward and away. The shape of the cam surface 112a is more specifically shown by a timing chart described later.

  The second cam member 114 is formed in a substantially disc shape, and has an upward cam surface 114 a that is uneven around the shaft 104.

  The second transmission mechanism unit 130 includes a second driven member 132 and a gripping operation force intermediate transmission member 136. The gripping operation force intermediate transmission member 136 is supported on the side of the shaft 104 by the movable support member Q so as to be movable in the vertical direction. This gripping operation force intermediate transmission member 136 is biased downward by a biasing member (here, a coil spring 136S). The upper end portion of the gripping operation force intermediate transmission member 136 extends sideways toward the cam surface 114a of the second cam member 114, and the second driven member 132 is supported at the tip portion thereof. The second driven member 132 has a driven roller 132a provided so as to be able to contact the cam surface 114a. Since the gripping operation force intermediate transmission member 136 is biased downward by the coil spring 136S, the driven roller 132a is normally in contact with the cam surface 114a.

  Further, a gripping operation force transmission roller 136 a that can come into contact with the gripping operation force receiving surface 157 of the gripping force applying unit 150 is attached to the lower end portion of the gripping operation force intermediate transmission member 136. When the intermediate gripping force transmission member 136 and the gripping force transmission roller 136a are in the upper position (see FIG. 18), the gripping force transmission roller 136a is located on the upper part of the gripping force receiving surface 157. By contacting, the position of the tip of the gripping force applying unit 150 is regulated so as to be disposed at a distance away from the one gripping member 72. In addition, when the gripping operation force intermediate transmission member 136 and the gripping operation force transmission roller 136a move downward from the above state, the gripping force transmission roller 136a can contact a portion of the gripping operation force receiving surface 157 from the outside. Thus, the distal end portion of the gripping force applying unit 150 can move toward the gripping member 72 so as to press the one gripping member 72. The gripping force applying unit 150 is moved toward the one gripping member 72 by the biasing force of the gripping force applying unit biasing member 158, and the terminal 20 can be gripped by the pair of gripping members 72 and 74.

  As a result, the second driven member 132 is driven to move along with the rotation of the second cam member 114, and the gripping force applying unit 150 is moved so as to press one of the pair of gripping members 72 and 74 accordingly. Become.

  Thus, the terminal 20 is gripped by the pair of gripping members 72 and 74 in a manner corresponding to the uneven shape of the cam surface 114 a around the shaft 104. Here, the cam surface 114a is formed in a shape for releasing the holding of the terminal 20 by the pair of holding members 72 and 74 after the temporary insertion operation. The shape of the cam surface 112a is more specifically shown by a timing chart described later.

  The third cam member 116 is formed in a substantially disc shape and has upper and lower cam surfaces 116 a that are uneven around the shaft 104.

  The third transmission mechanism 140 has a third driven member 142 and a displacement operation force intermediate transmission member 146. The displacement operating force intermediate transmission member 146 is supported by the movable support member Q on the side of the shaft 104 so as to be movable in the vertical direction. The upper end portion of the displacement operation force intermediate transmission member 146 extends laterally toward the outer peripheral portion of the third cam member 116, and the third driven member 142 is supported at the tip end portion thereof. The third driven member 142 has a pair of driven rollers 142a disposed so as to sandwich the third cam member 116 from both sides. As the third cam member 116 rotates, the third driven member 142 having a pair of driven rollers 142a moves in the vertical direction in accordance with the uneven shape of the cam surface 114a.

  Further, a displacement operation force transmission roller 146a that can contact the separation operation force receiving surfaces 167a and 167b of the separation force applying unit 160 is attached to the lower end portion of the displacement operation force intermediate transmission member 146. In a state where the displacement operation force intermediate transmission member 146 and the displacement operation force transmission roller 146a are at the upper side (see FIG. 18), the displacement operation force transmission roller 146a is from above the separation operation force receiving surfaces 167a and 167b. By contacting the portion, the position of the separation force applying portion 160 is regulated so as to be disposed at a distance away from the other gripping member 74. Further, when the displacement operation force intermediate transmission member 146 and the displacement operation force transmission roller 146a move downward from the above state, the displacement operation force transmission roller 146a moves the portion from outside the lower part of the separation operation force receiving surfaces 167a and 167b. Touching and pressing, the distal end portion of the separating force applying unit 160 moves to the gripping member 74 side so as to press the other gripping member 74. As a result, the pair of gripping members 72 and 74 and the terminal gripping portion 70 are displaced. As described above, the third driven member 142 is driven to move along with the rotation of the third cam member 116, and accordingly, the separating force applying unit 160 is moved so as to press the other gripping member 74.

  That is, the pair of gripping members 72 and 74 are displaced in a manner corresponding to the uneven shape of the upper and lower cam surfaces 116 a around the shaft 104. Here, the cam surface 116 a is formed in a shape that allows the pair of gripping members 72 and 74 to be displaced after the terminal 20 is gripped first by the pair of gripping members 72 and 74. The shape of the cam surface 116a is more specifically shown by a timing chart described later.

  In this way, the terminal insertion drive mechanism 100 performs the operation of first holding the terminal 20 supplied from the terminal supply port 50m by the pair of holding members 72 by the rotation drive of the motor 102, and then the terminal 20 is performed, and thereafter, the gripped terminal 20 is moved toward the circuit body 10 and inserted into the insertion recess 15.

<2.5. Operation of terminal insertion device>
The operation of the terminal insertion device 40 configured as described above will be described.

  FIG. 20 is a timing chart showing the operation timing of the terminal insertion device 40. The horizontal axis of the figure shows the elapsed time for one rotation of the motor 102. Further, the uppermost line in the figure shows the displacement amounts of the third driven member 142 and the displacement operating force intermediate transmission member 146 of the third transmission mechanism 140, and the second line from the top shows the first transmission mechanism. The displacement amount of the first cam member 112 of the portion 120 and the terminal gripping portion 70 is shown, and the third line from the top shows the displacement of the second driven member 132 of the second transmission mechanism portion 130 and the gripping operation force intermediate transmission member 136. Indicates the amount. These lines are the uneven shape of the cam surface 116a of the third cam member 116 in the direction along the shaft 104, the uneven shape of the cam surface 112a of the first cam member 112 in the same direction, and the second shape in the same direction. It can be said that the uneven shape of the cam surface 116a of the cam member 114 is shown. Further, the second line from the bottom of FIG. 20 indicates that the terminal supply mechanism 50 supplies the terminals during the hatched period, and the lowermost line in FIG. 20 indicates the circuit during the hatched period. It shows that the circuit body 10 is moved by the body support portion 48.

  First, in the initial state (t = t1, the rotation angle of the motor 102 from a predetermined origin position is 0 degree), as shown in FIG. 21, the terminal gripping portion 70 is between the tip portions of the pair of gripping members 72 and 74. Are arranged at a gripping position where one terminal 20 supplied from the terminal supply port 50m can be gripped. In this state, the gripping force applying unit 150 is in a state in which the one gripping member 72 is not pressed, and thus the pair of gripping members 72 and 74 are in an open state. Further, the separation force applying unit 160 is also in a state in which the other gripping member 74 is not pressed.

  In this state, one terminal 20 is supplied between the distal ends of the pair of gripping members 72 and 74 by the terminal supply mechanism 50. When the terminal 20 is supplied to such an extent that the terminal 20 can be gripped between the tip portions of the pair of gripping members 72 and 74, the motor 102 rotates from the initial state, and the third transmission is performed during the period from t1 to t2. The mechanism part 140 is slightly displaced, and the second transmission mechanism part 130 is displaced during the period from t1 to t3. At time t2, as shown in FIG. 22, the holding member 74 on the fixed side is slightly displaced by the pressing of the separating force applying unit 160. Further, at time t3, as shown in FIG. 23, the tip of the gripping member 72 on the movable side moves toward the gripping member 74 on the fixed side due to the pressing of the gripping force imparting section 150, and the tips of both gripping members 72 and 74 are moved. The press-fit portion 23 of the terminal 20 is sandwiched between the portions.

  In this state, as shown in FIG. 30, since the press-fit portion 23 of the terminal 20 is wider than the receiving groove 72g, the press-fit portion 23 is not accommodated in the accommodating groove 72g, and a pair of gripping members 72 is provided. , 74 is sandwiched between the tip portions.

  Thereafter, the third transmission mechanism 140 is further displaced between the times t3 and t5. At time t5, as shown in FIG. 24, this causes the pair of gripping members 72 and 74 to be displaced laterally relative to the terminal supply port portion 50m by the pressing of the separating force applying portion 160. In the middle of this displacement, an opening edge portion of the terminal supply port portion 50m is formed between the terminal 20 held by the tip portions of the pair of holding members 72 and 74 and the terminal 20 in front of the terminal supply port portion 50m. The shearing stress due to the gripping member 74 acts, and the terminal 20 gripped by the tip ends of the pair of gripping members 72 and 74 is separated from the terminal 20 in front of the terminal supply port portion 50m. At this time, since the gripping force applying unit 150 presses the gripping member 72 in a state of being biased by the gripping force applying unit urging member 158, when the pressing force of the separating force applying unit 160 is applied, the separation is performed. The gripping force applying unit 150 moves in the backward direction by the amount that the force applying unit 160 moves forward.

  In addition, the first transmission mechanism 120 and the terminal gripping part 70 move toward the circuit body 10 at times t <b> 4 to t <b> 8 when the terminal 20 is considered to be separated. Then, at time t8, as shown in FIG. 25, the connection portion 26 of the terminal 20 gripped by the distal end portions of the pair of gripping members 72 and 74 is inserted into the insertion recess 15 halfway (temporary insertion). Operation). In this state, the terminal 20 is inserted into the insertion recess 15 to such an extent that it can stand on its own.

  In addition, the gripping force applying unit 150 is moved in the backward direction by the transmission operation of the second transmission mechanism unit 130 at the time t7 to t9 when it is considered that the terminal 20 is inserted into the insertion recess 15 to such an extent that the terminal 20 can stand up. Become. Then, at time t9, as shown in FIG. 26, the pressing force on the holding member 72 is released, and the holding of the terminal 20 by the pair of holding members 72 and 74 is released.

  After the terminal 20 is released from gripping, the first transmission mechanism 120 and the terminal gripping part 70 move away from the circuit body 10 during a period from time t9 to t11. Then, at time t11, as shown in FIG. 27, the pair of gripping members 72 and 74 move away from the terminal 20 that is temporarily inserted into the insertion recess 15 and is self-supporting.

  In addition, at time t10 to t12 after the terminal gripping portion 70 starts to move apart, the separation force applying portion 160 moves backward by the transmission operation of the third transmission mechanism portion 140 and returns to the original position. 70 is also displaced in the same direction. Further, at time t10 to t12 after the terminal gripping portion 70 starts moving away, the gripping force applying portion 150 moves forward by the transmission operation of the second transmission mechanism portion 130, and the one gripping member 72 is moved in the closing direction. Press. Then, at time t12, as shown in FIG. 28, the connecting portion 26 above the terminal 20 is accommodated in the accommodating groove 72g of one gripping member 72, and the press-fitting portion 23 is at the tip of the gripping member 72. In a state of being positioned below, the terminal 20 is held (see FIG. 31). At this time, the receiving groove 72g may be omitted, and the terminal 20 may be sandwiched again between the pair of gripping members 72 and 74.

  Thereafter, at time t <b> 12 to t <b> 13, the terminal gripper 70 moves toward the circuit body 10 by the displacement operation of the first transmission mechanism 120. Then, at time t13, as shown in FIG. 29, in a state where the connection portion 26 is housed in the housing groove 72g of the gripping member 72, the tip end portion of the gripping member 72 presses the press-fit portion 23, and the terminal 20 is inserted deeper into the insertion recess 15 (main insertion operation). As a result, the press-fit portion 23 is press-fitted into the press-fit portion 15 b, and the terminal 20 is inserted and connected to the insertion recess 15 in a state where the press-contact portion 24 is press-connected to the electric wire 18.

  Thereafter, at time t14 to t18, the first transmission mechanism 120 and the terminal gripping part 70 move away from the circuit body 10 and return to the original gripping position. In addition, the gripping force applying unit 150 returns to the original position by the transmission operation of the second transmission mechanism unit 130 from time t14 to t15. As a result, the initial state is restored.

  It should be noted that the moving operation of the circuit body 10 is started at the time t16 during the return, and the next insertion recess 15 is disposed immediately below the terminal gripping portion 70 by the next time t6. In addition, the terminal supply operation is started at time t17.

  In the above description, the operation has been described on the assumption that the terminal 20 is used. However, the terminal insertion can be performed similarly for the terminal 20B having a long insertion portion 22B.

  That is, as shown in FIG. 32, when the insertion portion 22B of the terminal 20B is long, the insertion concave portion 15B is formed deeper by that amount, so that the press contact of the press contact portion 24 is completed in the state where the press fit of the press fit portion 23 is completed. The relationship of completion is the same. For this reason, as described above, the terminal 20 can be similarly inserted into the terminal 20B by gripping and inserting the terminal 20 with reference to the press-fitting portion 23 (temporary insertion and permanent insertion).

  Further, terminal insertion can be similarly performed for the terminal 20C having the relatively long connection portion 26C.

  In addition, when inserting other series of terminals 20D and 20E having different widths, the terminal insertion can be performed in the same manner as described above only by replacing the terminal supply mechanism 50 and the terminal gripping part 70.

  According to the terminal insertion device 40 configured as described above, when the terminal 20 is delivered from the terminal supply port 50m, the terminal 20 is gripped by the pair of gripping members 72 and 74. Then, the gripped terminal 20 is separated from the other terminals 20 in front of the terminal supply port 50m by the displacement of the pair of gripping members 72 and 74 with respect to the terminal supply port 50m. Thereafter, the terminal gripping portion 70 moves toward the circuit body 10 so that the terminal 20 is inserted into the insertion recess 15. Therefore, when the terminal 20 is inserted into the circuit body 10, a plurality of terminals 20 can be supplied in the form of the chain terminal 30 without separating the terminals 20 in advance, and the terminals 20 can be inserted. Can be easily handled.

  Further, since the terminal gripping portion 70 is detachably attached, it is possible to selectively attach a plurality of types of terminal gripping portions 70 prepared according to the type of the terminal 20 to be inserted and insert the terminal. it can. In addition, the gripping force applying unit 150 of the terminal insertion drive mechanism unit 100 applies a force to grip the terminal 20 by pressing one gripping member 72 from the outside of the terminal gripping unit 70, and the separation force applying unit 160 Since the terminal 20 is separated by pressing the other gripping member 72, the shape of the pair of gripping members 72 and 74 is somewhat different with respect to the plurality of types of terminal gripping portions 70 attached according to the type of the terminal 20. A force for gripping the terminal 20 and a separating force can be applied. Further, it is not necessary to incorporate a drive mechanism for applying these forces into the terminal gripping portion 70, and therefore the configuration of the terminal gripping portion 70 can be simplified.

  Further, since the gripping force and the separating force are applied by the rotational driving force of the motor 102 as a single driving source, the number of driving sources can be reduced, which contributes to cost reduction.

  In addition, after the terminal 20 is temporarily inserted, the terminal 20 is released from being gripped, and the terminal 20 is pushed in again to perform the main insertion. Therefore, the terminal 20 can be inserted deeper.

  In addition, since the rollers 152 and 162 are provided at the portions that press the pair of gripping members 72, the terminal gripping portion 70 can be smoothly moved while the pressing force is applied.

  In the above-described embodiment, the case where the operation related to terminal insertion is realized by a single drive source has been described. However, it is not necessarily required to be realized by a single drive source. Operations related to movement in the insertion direction, application of gripping force, and application of separation force may be realized by separate driving sources. As a drive source in this case, various configurations such as a motor and a linear actuator can be employed. In short, the terminal 20 supplied from the terminal supply port portion 50m may be separated by a shearing force or the like and inserted as it is.

  Also, the object is not limited to the terminals and circuit bodies having the above-described configuration, and is applied when various terminals supplied in the form of chained terminals are inserted into the insertion recesses of various circuit bodies such as printed circuit boards and bus bar boards. it can.
